' application-mea June 4.,

To all whom t may concern:

Be it known-thatl, CHARLES H. MELVIN, a

citizen of the United States, residingv at Moline, inl the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Wheeled Plows,

' of which the following is a specification, reference being had therein to the accompanying drawing. i

This invention relates to two-way sulky plows. Plows of this character are ,designed for plowingback and' forth along'jone sidel of a piece of land where it is impossible or undesirable to follow the usual method of plowing around the piece. Such plows have `al wheel frame and two plow bodies which,

are `usually arranged side by side with their moldboards extending in opposite directions. Means are provided to raise and lower the plows, and in operation one of the plows isV lifted to inoperative position whilethe other' is in use.

The principalobjects of the present in.

vention are, first, to provide improvedmeans for lifting the plows out ofthe ground, seci ond, to provide improved means for adjustably connecting lthe tongue to' the wheel frame, and third, to provide improved draft connections.

In the accompanying drawings, Figure 1 is a left side\elevation of the plow embodying my improvements, 'the ground wheel on the near side being omitted to better show some of the features of construction. Fig. 2 is a plan view of the plow. Fig. 3 is a right side elevation of the leftlifting lever lcured to the under side of the horizontal part la of the frame at the middle thereof.v This depending leg 3has its lower end in line with the lower ends of the legs 1b, 1.

is a transverse bar which stiffens the forward part` of the wheel frame and serves a furtherfunction to be referred tolater.

Upon the rigidwheel framevthus constitutedare mounted two Acranked axles 'each of which carries onerof the ground-wheels 'and one ofthe two plows.f.1nasmuch as each of the cranked axles and the ground` wheel, plow and, other moving devices associated therewith are substantially duplicatesfof lthe f;

other cranked axle, wheel,rplow1fandother, corresponding parts', it will -sufce to give a.

detailed 4description of one of the said groups of parts, and I shall refer in the following description more especially to theaxle, plow and other parts on the left side of the implement. 5 is van` axle., upon which is mounted the ground wheel 6. The axle 5 has a crank part 5, the 'inner arm of which is connectedby a pivot bolt 7 tothe dependf j ing leg 3 of the'wheel frame.- The outer arm of the crank part is not in the same transversel plane as theinner arm, but `asecond outer arm part 8, which is rigidly secured to the crank part of the axle isdisposed in the same plaine.l with `the inner crank arni of said axle and is pivotally connected by a bolt 9 to the. lower enol` of the framebar 1", said pivot bolt9 and the pivot bolt 7 having `a common axis. ,y

' 10 is a plow beam 11 with out-turned moldboard, The beam 10 carries a'bracke't 12 whichv is sleeved upon the crank part 5a of theaxle. By swinging the cranked l'axle 5, itwill be seen thatthe plow connected to it 'can' be raised and low-' ered, and to effect such swinging, VI provide the following devices: 13 "is a hand lever to which is ri`gidly`-`y secured a bracket 14 which extendsA forwardly and inwardly, and ispivotally connected to the lower` end of the frame bar `1b bynieans of the pivot bolt- 9. VThe lower end of the lever 13 is sleeved uponthe axle 5, and it willibe seen, therefore, that by throwing the hand lever for- `ward, the wheel axle'can be thrown back`- ward vand upward. 15 "is' a segmental toothed rack carried upon arms 16, 16, which preferably forma part of the casting 1. This rack is disposed adjacent the hand lever 13 and oope'i'ates with a locking bolt, o

lug 17 (see Fig, to secure the yhand lever in adjusted position. rlhe lug 17 vlis carried carrying the plow body1 lby a sliding sleeve A18 which is connected bv 1 his hands free to guide the'. team.- -The -immeans of a link 19 'with a linger lever 20 mounted upon the upper end of the h and le ver. 21 is a thumb lever, which 1s also pivote'd on the hand lever and has 'alost motion connection with the linger lever, as is clearly shown. A spring 22 presses the sleeve 18 upward and tends to mamtain the bolt 17 in engagement with the rack 15. By actuating the thumb lever 21, the bolt can be disengaged from the rack and the hand v lever freed to move upon its fulcrum.

sleeve 18. By moving the sleeve 18 downward, the lower 'end ofthe bolt 24 can be f moved into engagement with the teeth of the ratchet 23, thus locking the ground wheel 6 to the hand lever 13 and through it, to the cranked axle` 5. When such locking is effected, the draft of the team transmitted through the ground Wheel asthe latter ad` vances, is applied to the cranked axle caus-l ing -the latter to swing backward ward so as to lift the plow.

Heretofore it has been the practice to throw the bolt24into engagementwith the ratchet 23`by means of the finger lever 20, or some' equivalent hand operated device. One of the objects of my inventionis to provide devices for effecting this movement o f the'bolt 24 which shall be operable by the foot of the-driver, thus leaving'both of and upportance of this will be understoodwhen it is remembered that the plow' is lifted at the side ofthe field just atthetiie the driver is starting to turn around for'ftlie return trip across the field, The ydevices"'which I provide to the` end v.indieated','areias follows: 25 isa foot levermountediimbrackets 26 carrled by `theframe bar2and pivotally connected to a lever 27 which is pivoted at its forward endon the fra-me bar 2, and has its rearend connected to a link 28 which exi tends upward and has its upper end formed 1n the shape of a hook to engage, the slidying sleeve 18'on the hand lever. The lever 27 is so formed and mounted that its rear end lies approximately on the axis of the' pivotal bolts 7 and 9. In other words, the

.rear end ofthe lever,27 is coincident with the ax1s aboutwhich the hand lever swingsv so `that the hand lever can move independently of and without affecting the lever 27. The foot lever 25 is so disposed that it can easily be reached. b vf the driver when sitting in the seat 29, and when the drlver presses downward upon said foot lever, the rear end of the lever 27 is thrown downward carrying with it the sliding sleeve 18 on the hand lever 13,`thus causing, first, the disengagement-of the locking bolt 1T from the rack 15, and thereafter, the engagement of the bolt V24 with the ratchet 23. 'lhe wheel having thus been locked to the cranked axle 5, the latter is thus swung rearward and upward so as to lift the plow from the ground. For the purpose of automatically stopping the lifting movement of the plow, the rack 15 is formed with a cam extension 15, and the sleeve 18 of. the hand lever carries a roller 3() which engages said extension as the hand lever swingsforward so that the sleeve 18 is moved upward on thel hand lever, thus causing the disengagement of the bolt- 24. from the ratchet 23 whereupon the spring 22 is free to continue the movement of the sleeve 18 and cause the, bolt 17 `to engage a notch in the rack 15, thus lock- 'substantially duplicated on the otherside of the machine, and it will therefore be unfderstood that the plow on the right side of the machine is controlled and actuated by its associated hand and foot lever devices in the manner described in connection with the plow devices on the left 'side of the machine.

The plow is guided by means of a pole or tongue '31, which is pivotally com'iected at its rear end to abracket 32,`bolted lo the depending leg of the wheel frame.

33 is a bracket bolted to the lower side of the tongue and having a sliding engagement with the transverse part of the frame bar2.

34 is a link pivoted at its middle part to the bracket 33, and' at its left end to a bellcrank lever 35 mounted at the forward left corner of the frame bar 2. This bell-crank leveris connected by means of a link 30 to -a yhand lever 37.1nounted on a bracket 38 on .the wheel frame,.sa1d bracket beingformcd wilth a segmental locking rack 38", which cooperates with an ordlnary locking bolt on the hand lever to secure thelatter inadjusted po- ,.sition. Bv throwing the hand lever 37 liaekward and forward. the` tongue` 31 can be swung laterally, thuscausing the plow to take more orf less'land, a feature which is deisirable especially when working` on hill s1 es.

. horses on an implement of this kind, and to It is sometimes desirable to use three make this eas'ily' accomplished, I'provide 4a pivot bracket 39which isbolted to the vframe bar 1,"a'nd to'which the rear vend of the tongue'may. be pivoted; rather than 'to rthe bra'cket -32. 'When' this change 1s made, the' bracket 33 is pivotallyc'iinected" to the ex- `treme right end of 'thelink 34.' 'The tongue l "l' lever 37 as before.'

' l The draft devices, byj means of which the draft animalsfare'hitched to the 'plow"s, are peculiarly constructed asfol'lows: On the Ican then-be" angled" by 'means ofthe hand forwardv end of 'each Aplow Vbeam is pivoted ya bracket 40' which can be adjusted up and down toa limitedjextent, and secured inadjusted Vposition by means of the clamping bolt 41. To veach of .these brackets is secured an ordinary" clevis '42, andto these two lclevises 42 are loosely connected, asbyllnks 43,'thetwo endsfof a -rod'44. The main partl of the rod 4 4 is straight, but its ends are curvedbackward, as is clearly shown in Figs'flfand 2. i45 isa block l.carrying a pulley 46 adapted'to run upon therod 44,.

and 47 is a draft clevis ,having a swivel It will be noted onf'efeence to lithatf' the front end of the beam of the plow, which is lifted to inoperative position, isv higher' vthan-the front end of they beam o fhe other plow which is lowered` to working position. Because of this 'the clevis 47 and Lpulley 46,

Carrying as they` do the weight of the dou` bletrees, tend to Islideto that endo'f the rodA '44 which 'is connected tothelowerplow and thus the draft is applied'quite directly to -'the plow which is inoperative position, and 'iurthermore`, ythe/line ofdraft is shifted automatically from one f plo'wlto the other [when one is liftedandthe other'lowered.

The operationfof my improved plow will now be readily understood.` 0n arriving at Y When the plow has reached the desired depth,"the'thumb latch 21 is released and vthe hand lever locked in adjusted positionf the point in the field where'the plow is to be` started, the driver grasp's the thumb lever 21 of one or the other of the hand levers 13 and ls'wingsit rearward to lower the plow connected therewith, one or 'the other of the plows being lowered according as. the earth is 'to be thrown to thel right Lor the left.

A- s he 4plow isV lowered ythe" draft connections 4 46, 47, slide into line with' the beam of the lower plow, andthe draft of the team, as` the plow 'takes intothe ground, is appliedA directly to the beam of the plow. If

th'e plow body 'when thus lowered is level,

On reaching the turnlng point, the driver presses uponthefoot leverl 25 of the working plow thus disengaging the hand lever 13, and at the same time, locking the ground wheel to its axleand causing the axle to swing rearwardv and upward carry ing with it the plow. As the plow rises to' 4its full elevation, the lifting devices are automatically disengaged and the locking devices 'automatically applied in the-manner previously described. Then, the driver, having turned through 180, lowersthe other wheel axle, a groundwheel thereon, a plow r lhaving its beam connected with the main "frame solely through a pivotal connection with the swinging axle, means for locking.
